This study was conducted to determine the bacterial composition and its effect on Artemia performance in various biomass culture conditions. Newly hatched franciscana were cultured 1.5L plastic bottles containing 1L of medium, with a density 200 nauplii/L salinity 30 ppt, lasted for three weeks. In first two days after stocking, fed Chaetoceros sp. Afterward, Artemia-formulated feed used as dai...

Ž . The effects of high dietary docosahexaenoic acid 22:6ny3, DHA and varying arachidonic Ž . acid 20:4ny6, AA were tested on growth, survival and resistance to handling stress in 5–35 day old gilthead seabream larvae. Three enrichment treatments differing in their DHArAA ratios Ž . Ž were fed to rotifers Brachionus rotundiformis and Artemia nauplii. The high DHA 35.9% . Ž . TFA enrichment trea...

Ontogenetic changes in biomass and chemical composition were studied in the laboratory during the abbreviated larval and early juvenile development of the caridean shrimp Campylonotus vagans from the subantarctic Beagle Channel, Argentina. At 7F 0.5 jC, development from hatching to metamorphosis took about 44 days. The larvae started feeding on Artemia nauplii immediately after hatching, althou...

 Co-feeding of fish larvae with live food and formulated diet has been at the focus of fish nutritionists since last decade. In this study we tried to refine the feeding practices of great beluga sturgeon (Huso huso) larvae using different combinations of newly hatched Artemia urmiana nauplii and trout starter diet. Three replicate groups (250 fish/replicate) of first-feeding Huso huso ...

The current commercial production protocols for Atlantic cod depend on enriched rotifers and Artemia during first-feeding, but development and growth remain inferior to fish fed natural zooplankton. Two experiments were conducted in order to identify the underlying factors for this phenomenon. In the first experiment (Exp-1), groups of cod larvae were fed either (a) natural zooplankton, mainly ...
